On the 1st day, the paper and the mouth of the bottle must be tightly combined to prevent the newly hatched larvae from crawling and escaping. After most of the feed is eaten, new feed needs to be added in time. After 2-3 days of feeding, the cuttings are used for feeding. Cut the tea branches with tender shoots from the field, and insert them in bundles into a 500mL wide-mouth bottle filled with water. Put 3-4 bottles of tea branches close together in a plastic pot with a diameter of 60 cm to form a small tea canopy. The larvae (6 bottles) in the worm bottle are moved to the tea canopy, and allowed to spread and get food on the tea canopy. After the 4th age, add or replace tea sticks in a timely manner according to the feeding situat...
